F1 needs street circuits for variety. We don't want more soulless tracks in the middle of nowhere, so I think a maximum of 3 street circuits is good. So that's Monaco, a modified Singapore, and New York (drop Valencia). We still need traditional circuits like Spa, Silverstone and Monza, and f1 needs to move into huge potential markets like the USA. So we do need GP's like China, Russia, India, Malaysia and the USA. So (sorry for going a bit off topic) my calendar would be (based on inevitable future GP's):
1. Australia
2. South Africa
3. Malaysia
4. Abu Dhabi
5. Russia
6. Spain
7. Monaco
8. Canada
9. New Jersey
10. France
11. Britain
12. Germany
13. Hungary
14. Belgium
15. Italy
16. India
17. Singapore
18. Korea
19. China
20. Japan
21. Mexico
22. USA
23. Argentina
24. Brazil
For me, Argentina and Mexico a maybe, and with clever date working this could be a viable calendar (with a summer break) although there would be a lot of back-to-backs!
Great post mjo
Hope this works... the idea is that you should select as many circuits as you would have in your ideal season. You should be able to vote for as many or as few as you want if I understand it correctly...
